Be it known that I, ARTHUR O, OnHRL'n'a citizen of the UnitedStates of America, re
' Whether or not the knock in the motor is the result of a worn piston, a wrist pin. or a connecting rod bearing, the vacuum causing the.
loose part to movewithin the cylinder for this purpose.
' Thenatur'e and advantages of the, inven tion will be better understood when the following detailed descriptionis read in con-' nection with the accompanying drawings, the invention residing in the construction, combination and arrangement" of parts as claimed. v g In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:
Figure 1 is a fragmentary sectional View through a motor showing the pump associated therewith for the purpose above men- 'tioned.
Figure 2is a detail viewof the elbow connection for spark plug openings of a particular size.
Figure 3 is a similar view of a smaller connection for the same purpose.
Figure 4 is a view of a flexible connection used in conjunction with the pump for use, drawing carbon deposits from the cylinder.'
The device forming the subject matter of. this invention is adapted to be associated with a pump cylinder closed at one end by a cap 11 through which the piston rod 12 reciprocates, the latter being equipped with a suitable handle 13', and a piston as will' be readily apparent.
The pump may be used as an oil orgrease force feed pump, and when itis desired to fill the pump with grease, the cone shaped end portion 16, which is threaded on one end of the cylinder I" removed therefrom.

I y The primarylpurpose of the device for determining the icauseof a knock in a .1no'-' I tor, and the knock ,can be traced to, its respective cylinder, without} any guess work or uncertainty of leakage. For thispurp'ose vI make use of a short length of pipe 19 having one end threaded into the small end of the cone'shaped extension above referred to, and its other end threaded into an elbow coupling 20 as shown in Figures 2 and 3, thesecouplings are threaded at one end as at 21 to accommodate themselves to the spark plug openings of the cylinder blocks, the coupling inv Figure 3 being slightly smaller than the coupling in Figure 2, so that the device can be used with either I one-half or seven-eighth inch spark plug openings as Will be readily understood.

stopped. The motor is then turned over by the crank until the piston inthe particular cylinder to be tested reaches the limit of its compression stroke or the point where the In using the device for the purpose just.
explosion occurs, at which point most wear is found. The spark plug is thenremoved," and the device associated withthe motor in the manner shown in Figure 1. 'The plunger is quickly reciprocated, creating a vacuum within the cylinder, and causing a rocking effect upon the part or partscausing theknock. In other words, an experienced automobile repairman by carefully listening to the noise resulting from the formation of a vacuumin the cylinder in the manner described, can readily determine whether the knock in the motor is due to a worn piston;
a wrist pin, or connecting rod bearing.
In addition to using the device in the v capacity above mentioned, I provide a flexible tubing 22 which can be coupled with the I cone shaped extension in place of the short length of pipe19, This flexible tubing is then introduced into the firing chamber of a cylinder through the spark plug 0 ening, and by reciprocating the piston, car on de posits. which have been scraped from the cylinder or withdrawn therefrom, into the cylinder 10,0f the device. 7
the foredescribed and that such changes may be resorted to when desired as fall Within the scope of what is claimed.
Having thus described the invention, I claim: p
In a device of the character described, a pair of tubular elements each of \vhichis provided with exterior screw threads at one end and one of which has interior screw threads to receive the adjacent threaded end of the other section, and the other exterior screw threaded end being adapted to be received in the spark'p'lug opening of an internal combustion engine cylinder,
wrench engaging surfaces formed upon each of the tubular sections, a lateral nipple formed upon the upper end of one of the sections, and a conduit having a portion of its length in alignment with the nipple and engaged therewith, and the remainder of its length extending upwardly at an oblique angle with respect to the vertical and adapted to communicate with a pump barrel.
In testimony whereof I aifix my signature.
